. 13 Claims. (Cl. 5-351) The invention coinprehends a mattress which is constructedand arranged to'provide a comfort able and resilient support throughout the entire areaof the upper surface thereof, which will depress in accordance with the contour of the body disposed thereon-seas to conforni therewith with-} out distortion 'of the portionsof the inner-structure or the-mattress surrounding the depressed area and which includes a flexible "and-'resilient-j peripheral portion adapted'to permit of the convenient-insertion of the edge portion of the bed clothingithereunder.

Another object of innerspring mattress construction which takes the place of and accomplishes the results obmattress and box pring; bed or open coil springs and the'like.

the invention is to provide an l tained by the usual combination'of' innerspring Another object of the invention is toprovide an innerspring'unit including upper and lower springs so arranged' that the lowersprings resiliently support the'uppe'r springs and-the uppersprings are rela tivelymore flexible than the'lowersprin'g's Another object of the' invention is to provide an innerspring unit" including upper and I lower springs surrounded at their-edges by a row of border-springs i which a are substantially e'qualin length to the combined length of said upperand lower springs. Y

Another object of the invention i to provide an innerspring unit including upper springs arranged with their axes disposed vertically and lower springs arranged with their axesdisposed horizontally and which latter springs resiliently support the upper springs. T

Still another object of the invention is to provide an innerspring unit of saidcharact'er including an intermediate frame afflxed to the medialconvolutions of the border springs and af-' fixed .to the'adjacent ends of the upper and lower ing the lower spring members to said lower frame and tosthe intermediate frame. 7 a a I With'the'foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment'of the invention is illus tratedgr i Inthedrawings: I V v.

includes upper and lower springs I4 and I5 pref-.3.- erably arranged in longitudinally and transversely: extending rows throughout'a rectangular arearofg J the innerspring unit.) i Q The springs I4 are'spaced apart in the'longitudinally and transversely; extending rows .andareof a length substantially half the thickness ofthe innerspring unit. The said springs are preferably of-spiral formation with the c nvolutions decreasing in size from the top to the bottom thereof. The uppermost convolutions of the said springs are disposed in a common plane and said springs have their axes disposed vertically when the mattress is arranged in horizontal bed formin condition.

The lower springs I5 are also spaced apart in the longitudinally and transversely extending rows and :thesame preferably are of bowed or semicircular formationhaving their axes disposed at right angles to the vertical axes of the coil springs I4 and extending horizontally when the mattress is arranged in horizontalbed forming condition.

Surrounding the rectangular area embracing the upper and lower springs and'1'5 is ape ripheral row of border springs IB which are of coil formation having their convolutions decreasing in size from their upper and"lo'wer"convolu-" tions toward the medial convolutions I1 respec; tively and the same are of a length substantially equal to the combined length of the upper and lower springs- I4 and I5. The said border springs are arranged with their uppermost convolutions I8-disposed in the plane of the uppermost convolutions-I9 of the upper springs I4 and have their axes disposed parallel with the axes of thev upper springs I4 and extending vertically when the mattress is disposed in horizontal bed-form ing condition. 'Upper and lower wire members 20 and 2| surround the border springs I6 and are;se-1' cured to the-outermost convolutions thereof by clips 22 or equivalent fastening means to thereby reinforce the upper and. lower peripheral edges 1 oft the, innerspring unit and provide upper and lower rectangular border frames about which the inner-fabric casing II is formed.

Arranged-between the upper and lower springs I I4 and I 5 is an intermediate frame indicated generally by the reference character'23 which.con-' sists of longitudinally and transversely extending strips 24 and 25. The longitudinally extending strips 24 correspond in number to the number of longitudinal-rows ofupper springs :I4 and border springs I 6, while. the transversely extending strips 25 correspond in number to the transverse rows" of fupper springszl l. The longitudinally extend ins; strips. 24 cross the transversely extendingf: strips 25 centrally below the lowermost convolu tions 26 oftthe upper springs I 4 which areisecu're'd thereto by longitudinally.spaceditongues 2'Lstruck' upwardly from the body of the longitudin'ally'ex tending-strips and;:bent downwardly into overlying clampingirelation with the lowermost con-" volutions 26. The two outermost longitudinally extending strips 24 cross the transversely extending strips: adjacent theirouter ends centrally be low-*the:mediahconvolutions I! of the-two longi'-- tudinally'extending. rows ofborder springs 1 I 6 and l the-.sameare secured to the outermost 'longitudi nally extending ljstrips :24 by"similar-'upstrucktongues121 which are bent into clamping overlying relation with the medial convolutions '11" thereof; I The longitudinally extending strips 24 projecti'ce'ntrallyunder the medial convolutions I 1* ofx thex border :rsprings I6 in the a two outermost" transverse rows of border springs and which are secured to'theborder springs l6 in'said rows by up'strucktton'gues 21 clampingly engagingover the medial convolutions I I thereof.

springs adjacent the intermediate longitudinally extending strip 24.

The innerspring unit also includes a lower frame indicated generally by the reference char acter'35 which is-of rectangular formation..-and,- corresponds to the rectangular area of theyuppenand lower springs I 4 and- I5 whereby the sides 36 and the ends3'Iof the frame-underlie". theoutermost-longitudinal and transverse rows ofthe lower springs -.I5.

U-shaped formation in cross-sectional configuration and the said frame isiprovided -withtrans versely extending. bars-38-secured at their ends to' the sides 36 thereof and which are also ofin-r. yerted -U-shaped .formation in-,cross sectional-.-. configuration.
